Power Pages: Update Your Portal Auth Key Before Expiry

I saw the below Notification recently, while I was working on the Microsoft Portal requirements.

Notification

The authentication key for your portal will expire on 8/5/2025 6:24:53 AM UTC. Expiration of the authentication key will result in downtime of the portal because it won’t be able to connect to Dynamics 365 (online).

Actually, when you create a website with Power Pages, it connects to Microsoft Dataverse using an authentication key. This key is generated when the website is created, and the public part is uploaded to Microsoft Entra. You need to renew this key every year. If you don’t, your website will stop working once the key expires.

The article will explain the process to renew the Website Authentication Key step by step.

Follow the steps below.
